    How to Integrate [1/(x^2 + 1)] dx?

    hi! v olso have a drct frmila for these kind of ques...i.e.integration[1/(a^2 + x^2)]dx = (1/a)(arctan (x/a)...so you can assume a=1 here and hence the ans wud b 'arctan x'...

    How to Integrate [1/(x^2 + 1)] dx?

    there is a direct formula for these kind of questins i.e integrate[1/(a^2+x^2)]dx = 1/a[arctan(x/a)] so u can assume a=1...so ur ans vil b (arctan x)...jst dis..
